WINDOW -SCREEN.

SPECIFICATION forming part of Letters Patent.No. 443,092, dated December23, 1890.

Application filed December 14, 1889. Serial No. 333,778. (No model.)

To all whom it may concern.-

Be it known that I, CHESTER K. HANN, a citizen of the United States,residing at C0- lumbus, in the county of Franklin and State of Ohio,have invented a certain new and useful Improvement in Window Screens, ofwhich the following is a specification.

My invention relates to the improvement of window-screens, and hasparticular relation to the improvement of the device shown in my form erapplication, Serial No. 317,358, allowed on the th day of November,1889.

The objects of my present invention are to so construct and arrange awindow-screen of this class as to admit of its parts being readily andeasily adjusted for use in windows of different widths, toproduceaspring-actuated screen of superior construction without the useof the ordinary spring-curtain roller, to simplify the constructionshown in said former application, to produce a superior form ofadjustable case and caps therefor, and to provide guides for the edgesof the screen.

These objects I accomplish in the manner illustrated in the accompanyingdrawings, in which- Figure 1 is an interior elevation of a window havingmy improved screen thereon and showing the lower window partiallyraised. Fig. 2 is a central vertical section of the same. Fig. 3 isasectionalview taken on lineocof Fig. 4.. Fig. 4: is a longitudinalcentral section of the roller-case, showing the rollerin elevationtherein and its screen removed therefrom. Fig. 5 is a side elevation ofone of the covercaps. Fig. 6 is a view in elevation of a portion of thecover-case. Fig. 7 is a transverse section of the same. Fig. 8 is atransverse section of the screen end strip, taken on line in 00 ofFig. 1. Fig. 9 is-a transverse section one of the side pieces of thewindowirame, taken 011 line .2 .2 of Fig. l to show the screenguide.Fig. 10 is a view in perspective of a window-sash strip which I use inconnection with my device; and Fi 11 is a transverse section taken online y y of Fi 4, showing in addition the screen wound upon the roller.Fig. 12 is a detail view in perspective of one of the roller-pivot pins.

Similar letters referto similar parts throughout the several views.

Ct represents a roller of the general form of a curtainroller. Thisroller is divided at or nearits central portionto formtwo sections,theinner end of oneof said sectionshavingasocket and the adjoining end ofthe remaining section being cut away to form a pin or dowel I).

The two sections of the roller are joined, as shown, by having the dowelof one section inserted the desired distance within the socket of theother, said sections being held in this position by means of suitabletacks or pins 0, which extend through the wall of the socket and intothe dowel.

The outer end of each of the sections of the roller a is provided with apin-socket d, the latter being square or angular in cross'section.

Upon the roller 01- is wound and secured at one end a screen said screenbeing formed of any desired flexible material.

Surrounding the roller a and the screen f wound thereon is a cylindricalcase or cover g, which is preferably formed of thin metal, and which isformed, as shown, throughout its length with a longitudinal slot g. Thelongitudinal edges of the case C, produced by the formation of the slotg are, as shown in Figs. 6 and 7 of the drawings, bent over until inclose proximity to the outer surface of the case, thus formingstop-grooves 72, for

the purpose hereinafter specified. The case g is also formed in twosections, the inner ends of said sections being adj ustably connected bymeans of a collar 2', which is of the same form in cross-section as thecase-sections,with the exception that the stop-grooves are omitted, andhas its longitudinal edges entering and abutting against thestop-grooves 72 This collar is of such circumference as to inclose theinner ends of the case.

k 70 represent case end caps, one of which is adapted to fit over eachof the outer ends of the case-section. Each of these caps, 'consists ofa disk provided with a circumferential flange, and is made to inclose,as shown, a coil-sprin One end of this coiled spring is riveted orotherwise secured to theinuer face of the cap-flange, while itsremaining end is secured to a pin a, the latter having one of itsends,which is round in cross-section, journaied. in the center of thecap it, from which it projects inwardly and having its 16111&lll ingend, which is square in cross-section, as shown in Fig. 12 of thedrawings, entering the socket (Z of the roller. The flange of the cap itis provided with an open slot 7.:'.

The screenf has one of its ends secured to the roller (1, and passingoutward through the slot of the case has its remaining end socured to anadjustable cross-strip q. This cross-strip q is, as shown, formed of twosections, each of which is bent somewhat in the form of a block letterC, and one of which is of such size as to fit and slide snugly withinthe other, as shown in Fig. 8 in detail of the drawings. The outer endof the screen is clamped firmly between the bent edges and the bodies ofthe strip-sections q. ()ne of the caps 7c is slipped over each end ofthe case g, the pin it extending within the socket (Z of the roller, andthe parallel edges of the cap formed by the slot 7; are made to enterand abut against the stop-grooves 71, in order to place the spring I andthe roller with which it is connected by the spring 177 underspringtension. The case adjoining its slot g is temporarily pressed orsprung inward from engagement with the cap to admit of said cap beingrotated at sut'licient number of times to coil the spring I more tightlyabout its pin 12. The edges of the slot is are then brought again intoengagement with the stop-groove to prevent the rotation of said cap.Secured to and formed on the periphery of each of the caps L is aprojecting lug k Although, as will hereinafter be seen, my improvedscreen and its parts may be used at either end of a window, forconvenience I have shown and described the screen which is adapted to beused in connection with the lower sash.

The herein described case and inclosed roller is secured upon the windowseat or sill a by inserting projecting lugs or feet k beneath the headsor staples h the latter being driven into the window-sill. In solocating the case its slot g is made to face the sash. The screenpassing outward through the slotted openings 7c is made to pass upward,its edges extending within the open vertical slots or grooves ofvertical guidestrips 3, one of which is secured to the inner face ofeach of the inner window-strips f. The crossstrips (1 of the screen areprovided with eyes q, with which are made to engage theupwardly-projecting hooksrfiof the lower crosspiece of the lower sash.It is obvious, however, that the screenstrip may be detachablysecuredorconnected in any desired manner different from that herein described.From the construction herein shown and described it will readily be seenthat the raising of the lower sash 4 will result in the screen beingpulled upward with said lower sash and the opening beneath the samebeing completely closed by the screen.

In order to close the space which exists between the upper and lowersash when the lower sash is not entirely raised, I employ a transverseflexible strip 1', preferably of thin rubber, said strip being securedto the under side of the upper sash It, and of such width as to projectinwardly and into contact with the glass of the lower sash, as is shownmore clearly in Fig. 2 of the drawings.

Owing to the fact that the two sections of the casegare connected by acentral collar 2, it is obvious that the sections maybe drawn from orpushed toward each other to lengthen or shorten the case to adjust itfor use in window-frames in different widths. 13y removing tacks c,which connect the two sections of the roller a the length of said rollermay be changed by pulling outward or inward said sections and againconnecting the same by said tacks when at the desired length.

The screen cross-strip q being formed in sections, which slide onewithin the other, it is evident that a similar adjustment may be made ofsaid cross-stri p.

From the construction shown and described it will be seen that as thescreen is drawn up ward from its case the revolution of the rollercaused thereby will impart a rotary motion to the pin ends, which,through their connection with the springs Z, will operate to increasethe tension of the latter. This tension of the springs will result inthe prompt taking up or winding of the screen upon the roller as thesash is lowered.

It is evident that one of my improved screens may be used in connectionwith the upper sash by securing the case 9 to the upper end of thewindow-frame and making the same connection of the screen and upper sashas that described for the lower sash.

During the winter months, orat times when the screen is not considerednecessary, it may be detached from the sash and its case withdrawn fromits connection with the windowframe.

By the construction and arrangementherein shown and described it willreadily be seen that the means of accomplishing said adjustments aresimple in form, inexpensive, and do not mar the appearance of thedevice.

Having now fully described myinvcntion, whatI claim, and desire tosecure by Letters Patent, is

In a window-screen, the combination, with the roller at, havingadjustable sections and end pin-sockets, screenf, secured and wound uponsaid roller, slotted case 9, formed of sections of equal diameters, andslotted collar t, adjustably connecting said case-sections, of slottedcase-caps 7;, pins 72, entering sockets (Z, and coiled springs I,connectingsaid pins and caps, substantially as and for the object setforth.
